Replace fast-xml-parser dependency in browser with window.DOMParser

[AllanZhengYP]

Describe the feature

Currently the fast-xml-parser is used by AWS-SDK to parse the response payload from XML protocol into JS object. This dependency is also included in the browser bundles. The dependency is a 17 KB tree-shaked and 5.5 KB Gzipped package.

However, the SDK in browser can get rid of this dependency by using the window.DOMParser and a v2-style adaptor layer to achieve the same purpose, can with size that can hardly go over 1 KB after Gzipped. The v2 implementation is proven reliable.

Use Case

The fast-xml-parser dependency will be included whenever XML protocol clients in bundled for browser.

Proposed Solution

As mentioned above, the browser xml parser can be replaced by porting the v2 XML parser that based on window.DOMParser to the v3.
